Uses of Interface java.util.function.IntFunction (Java SE 15)

Packages that use IntFunction
Package	Description
java.util	Contains the collections framework, some internationalization support classes, a service loader, properties, random number generation, string parsing and scanning classes, base64 encoding and decoding, a bit array, and several miscellaneous utility classes.
java.util.stream	Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.

Uses of IntFunction in java.util

Methods in java.util with parameters of type IntFunction
Modifier and Type	Method	Description
`static <T> void`	Arrays.`parallelSetAll(T[] array, IntFunction<? extends T> generator)`	Set all elements of the specified array, in parallel, using the provided generator function to compute each element.
`static <T> void`	Arrays.`setAll(T[] array, IntFunction<? extends T> generator)`	Set all elements of the specified array, using the provided generator function to compute each element.
`default <T> T[]`	Collection.`toArray(IntFunction<T[]> generator)`	Returns an array containing all of the elements in this collection, using the provided `generator` function to allocate the returned array.

Methods in java.util.stream with parameters of type IntFunction
Modifier and Type	Method	Description
`IntStream`	IntStream.`flatMap(IntFunction<? extends IntStream> mapper)`	Returns a stream consisting of the results of replacing each element of this stream with the contents of a mapped stream produced by applying the provided mapping function to each element.
`<U> Stream<U>`	IntStream.`mapToObj(IntFunction<? extends U> mapper)`	Returns an object-valued `Stream` consisting of the results of applying the given function to the elements of this stream.
`<A> A[]`	Stream.`toArray(IntFunction<A[]> generator)`	Returns an array containing the elements of this stream, using the provided `generator` function to allocate the returned array, as well as any additional arrays that might be required for a partitioned execution or for resizing.
